BROMINE
Chemical Designations - Synonyms: No common synonyms; Chemical Fomla: Br2.
Observable Characteristics - Physical State (as nomlly shipped): Liquid; Color: Dark red; red-
brown; Odor: Sharp, harsh, penetrating.
Physical and Chemical Properties - Physical State at I5 'C and I atm. : Liquid; Molecular Weight:
159.81; Boiling Point at I am.: 138, 58.8,332; Freezing Point: 19, -7.2,266; Critical Temperature:
Not pertinent; Critical Pressure: Not pertinent; Speczjic Gravity: 3.12 at 20°C (liquid); Vcylor (Gas)
Density: 5.5 at 20°C; Ratio of Specijic Heats of Vapor (Gas): 1.3; Latent Heat of Vaporization: 80.6,
44.8, 1.88; Heat of Combustion: Not pertinent; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Chemical safety
goggles, face shield; self-contained air-line canister mask; rubber suit; Symptoms Following Exposure:
SKIN: contact with liquid or vapor may cause acne and slow-healing ulcers. INHALATION: induces
severe irritation of the respiratory passages and pulmonary edema. Probable lethal oral dose fro an
adult is 1 ml. A brief exposure to 1000 ppm may be fatal; General Treatment for Exposure: SKIN AND
EYES: wash well with water and sodium bicarbonate solution. RESPIRATORY SYSTEM: if there is
obstruction to breathing establish airway by pulling tongue forward, inserting an airway tube, or doing
a tracheotomy; begin artificial respiration; if difficulty in breathing is a result of pulmonary edema,
treatment should be carried out with the patient in the sitting position. Administration of oxygen is most
important; INGESTION: do not induce vomiting. Have victim drink water and milk; Toxicity by
Inhalation (Threshold Limit Value): 0.1 ppm; Short-Term Exposure Limits: 0.4 ppm for 30 min.;
Toxicity by Ingestion: Not pertinent; Late Toxicity: None; Vapor (Gas) Im'tant Characteristics: Causes
severe eye or throat irritations which cause eye or lung injury; cannot be tolerated even at low
concentrations; Liquid or Solid Irritant Characteristics: Severe skin irritant. Causes second- and third-
degree burns on short contact; very injurious to the eyes; Odor Zlreshold: 3.5 ppm.
Fire Hazards - Flash Point: Not flammable; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Use water spray to cool exposed containers and to wash spill away from a safe
distance; Fire Extinguishing Agents Not To Be Used Not pertinent; Special Hazards of Combustion
Products: Toxic and irritating gases are formed when heated or in fires; Behavior in Fire: Not
pertinent; Ignition Temperature: Not flammable; Electrical Hazard Not pertinent; Burning Rate: Not
flammable.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: Reacts
violently with aluminum. May cause fire on contact with common materials such as wood, cotton,
straw. Iron, steel, stainless steel, and copper are corroded by bromine and will undergo severe
corrosion when in contact with wet bromine. Plastics are also degraded/ attacked by bromine except
for highly fluorinated plastics which resist attack; Stability During Transport: Stable; Neutralizing
Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymriza-
tion: Not pertinent.
